Distributed photovoltaic intelligent sewage equipment

Technical Field

The utilization of new energy is limited by the technology, and cannot play a great role in a short time. The great utilization and exploitation of energy causes great damage to the environment. Meanwhile, China is also a country with serious water shortage, more than 80% of rivers in China are polluted in different degrees at present, more than 400 cities in 660 cities in China are lack of water according to statistics, two thirds of cities have insufficient water supply, and meanwhile, most dispersed areas are not in place or are not put into use for sewage treatment construction, so that the pollution to surface water and underground water is caused by random sewage discharge.

China in 9 months in 2020 announced to the world the goals of achieving "carbon peak reaching" 2030 and "carbon neutralization" 2060 ago at the Federation. The realization of 'carbon peak reaching' and 'carbon neutralization' is that clean energy replaces the traditional fossil energy, and the carbon emission is reduced from the beginning of energy production. Photovoltaic power generation meets the requirements, and meanwhile, compared with the traditional commercial power, the photovoltaic power generation is simple in power generation process and free of fuel consumption. The equipment used by the distributed sewage in most areas still has higher operation and maintenance cost, large floor area, longer construction period and installation of equipment with complex construction. The combination of sewage treatment and photovoltaic power generation is only applied to large-scale sewage treatment plants, and the application and practice of adding photovoltaic power generation are lacked. Therefore, the effective process combining the simple operation and the pollution control effect with the clean energy mode is urgently explored.
